Hello! I woke up yesterday with a pain in my back on the left side between the mid of the back and the upper part of my back. It accures when I take deep breathes, cough or sneeze. It also hurts when I lay on my left side. I didnt lift anything this past weekend. I called the doctor but wont because to get in until next week or the week after. I was wondering shoudl I give it sometime because it might be a muscle or go to another doctor. I have tried a heating pad and that didnt help and I've taken pain reliever and that hasnt helped either.
